People can use the line if they feel unsafe, at risk or unable to cope without professional advice.

The phones will be manned by trained mental health advisors and clinicians who will work with people to mange their difficulties.

Reducing hospital admissions

Sonya Clinch, service manager for access and urgent care at WLMHT, said: “The new single point of access is great news for our mental health services. It’s easy to use, and provides the right help for people when they need it most.”

In an emergency, the SPA service, which aims to reduce hospital admissions, will respond within four hours, and within 24 hours in urgent cases.

The SPA will also ensure all referrals from GPs and carers are processed and responded to in a timely way, following a robust clinical triage process.

The service hopes to give more people a quick response and the chance to recover at home or close to home instead, with friends and family nearby.

Dr Beverley McDonald, chair of the North West London mental health and wellbeing transformation board, added: “This is a really positive step towards improving access to mental health services in Ealing, Hammersmith and Fulham and Hounslow.

“Ensuring that everyone from carers and patients to GPs, ambulance crews and the police have easy access to help and support during a mental health crisis is essential.”

Further support through GPs and in the community is also being developed, so professionals can step in earlier before things get to a crisis point.

The first recovery house for people who need intensive support was opened at Amadeus House in Ealing.
